摘　　要：多用户特征是交互桌面的核心特征.多用户围绕交互桌面进行面对面协作过程中体现出一些新的协作方式,这种体现新型协作方式的界面是一种新型界面设计范型,即"协作式界面".分析了协作式界面的并发操作等6个特征和5种新型协作方式.在设计方面,提出了协作式界面的设计范型,并采用层次状态机对典型协作方式进行了形式化描述与设计.在实现方面,构建了一套体现上述协作特征和协作方式的控件库,基于该控件库实现了2个示例性应用.最后开展了用户实验,并利用李克特量表对实验进行了统计,结果表明,基于交互桌面的协作式界面设计在决策质量、协同标绘效率、协作可视化能力方面都提高了60%以上,效果显著.The multi-user characteristic is a key factor for interactive tabletops. Some emerging collabora- tive patterns emerge during the process of multiple users gathering around interactive table and collaborating face to face. The interface which shows the emerging collaborative pattern is a design paradigm of emerging in- terface, which is called ＂interactive interface＂. 6 characteristics and 5 emerging interactive modes, including concurrent operation of interactive interface and so on, were analyzed. In the aspect of design, the design par- adigm for collaborative interface was proposed, and typical collaborative patterns were formally descrlpted and designed with hierarchical state machines. In the aspect of implementation, a set of component libraries em- bodying the collaborative traits and collaborative modes above were developed, and two typical applications were embodied based on these component libraries. Finally, user experiments were conducted, and experi- ment data were analyzed by Likert Scale. The results show that collaborative interface design based on interac- tive tabletops can improve decision quality, the efficiency of collaborative situation sensemaking and the visu- alization effect increase by more than 60% , the effect is significant.
